Minnesota Cannabis Laws 2026: What's Legal for Adults and Patients

Minnesota lawmakers legalized recreational cannabis with HF 100, which took effect on August 1, 2023. Tribal nations opened the first stores, and state-licensed retail sales began on September 16, 2025. Medical cannabis has been legal since 2014. The Office of Cannabis Management (OCM) regulates both markets.

Is weed legal in Minnesota?

Yes, for adults 21 and older. Bring a valid ID showing you're 21+. Visitors can buy too.

How much can you carry and keep?

Limit	Adults 21+
In public	Up to 2 ounces of flower, 8 grams of concentrate, and 800 mg of THC in edibles
At home	Up to 2 pounds of flower

Carrying more than 2 ounces, up to 4 ounces, is a petty misdemeanor with a fine.

Where can you use it?

Private property, with the owner's permission. Using cannabis in public places, in a car, or anywhere smoke could reach someone under 21 is not allowed, and cities can set their own rules and fines. Landlords can ban smoking.

Can you grow cannabis at home?

Yes. Adults 21+ can grow up to 8 plants per residence, with no more than 4 flowering at a time. Plants must be in an enclosed, locked space out of public view.

Medical cannabis in Minnesota

The medical program is now run by the OCM. Patients can buy smokable flower and other products, and medical purchases are exempt from the 10% cannabis tax and sales tax.

Taxes on cannabis in Minnesota

Adult-use purchases carry a 10% cannabis gross receipts tax plus Minnesota's regular 6.875% state sales tax and any local sales taxes. Medical purchases are tax-exempt.

Driving, work and housing

• Driving: Driving impaired is illegal, and open packages of cannabis in a car are banned.
• Work: Minnesota protects most workers from being punished for using cannabis off the clock. Employers can still ban use and impairment at work, and safety-sensitive and federally regulated jobs are exempt.
• Housing: Landlords can ban smoking and growing.

Old marijuana convictions

Minnesota automatically expunged tens of thousands of low-level cannabis records, and a Cannabis Expungement Board reviews felony cases for possible expungement or resentencing.

Is anything changing in 2026?

The retail market is still growing as the OCM issues more licenses. Possession and home-grow limits haven't changed.

Federal law in 2026

Federal law still treats recreational cannabis as illegal. In April 2026, the federal government moved marijuana sold under a state medical license (and FDA-approved cannabis medicines) to Schedule III, but adult-use cannabis is still Schedule I. That means it's still banned on federal land and can't legally cross state lines, even between two legal states.

Separately, a federal ban on intoxicating hemp products takes effect in two steps: synthetic and converted cannabinoids like delta-8 lose their legal status on November 12, 2026, and naturally derived hemp THC (THCA flower, hemp delta-9 edibles and drinks) on December 11, 2026.
